The only good news for Trump is that the public doesn't think much of the Democratic Party either. Six in 10 also think Russian Federation tried to influence the campaign, and among those who say so, 67 percent think Trump aides helped, similar to results in April.
The previous worst approval rating after half a year in the White House was 39 per cent, given to Gerald Ford in 1975.
The poll questions also revealed that 48% of respondents feel the country's leadership has become weaker under Trump, while just 27% believed it has become stronger, and 55% of respondents did not think the president was making significant progress towards his goals. Trump has become the most unpopular US President in last 70 years of the US history.
Almost half of respondents - 48 per cent - said they "disapprove strongly" of the president's performance in office, a low level never reached by ex-presidents Bill Clinton or Barack Obama, both Democrats, and reached only once by George W Bush, during his second term. A sampling: Two-thirds of those polled said they don't trust him to negotiate with world leaders.More news: Call of Duty: WWII Zombies' trailer has leaked, developers not happy
Just seven percent of Republicans said the Trump campaign intentionally helped Russian efforts, compared with 65 percent of Democrats.
The Post-ABC poll finds 60 per cent of Americans think Russian Federation tried to influence the election outcome, up slightly from 56 per cent in April.
But then, these basement-level numbers are nothing new for Trump.
That poll, released on the eve of the vote, showed Hillary Clinton leading Trump by 4 points (47 percent to 43 percent) nationally. Meanwhile, fewer than 4 in 10 say the Democratic Party now stands for something, while a slight majority say it "just stands against Trump".
His failed election promise to "immediately" repeal and replace Obamacare has also hurt Mr Trump, with 50 per cent of Americans indicating they prefer the current health care law over the Republican replacement.
